I wonder if anyone have some ideas about how to solve this geoprocessing situation:

1: I have a raster layer called mixlyr_apr (representing depth values)

2: I have a series of raster layers called: vv_10_apr; vv_20_apr; vv_30_apr; vv_40.2_apr; vv_55.5_apr; vv_78.5_apr; vv_113_apr and vv_242.6_apr (representing vertical velocity for a particular depth)

All rasters have the same extent, cell size, etc.

Say, for example, the cell value of mixlyr_apr is 60. In that case I need to produce a raster layer with the average values (per cell) of the vertical velocity layers that represent the depths below the value of the mixlyr (60 in this case). That is to say, the average values (in this case) of vv_10_apr; vv_20_apr; vv_30_apr; vv_40.2_apr and vv_55.5_apr

Hope doesn't sound too confusing and some of you can suggest some ideas.

Many thanks

what software are you using? –  mwil Sep 12 '13 at 16:02

One of the more efficient solutions uses your software's analog of the Spatial Analyst LessThanFrequency function. –  whuber Sep 12 '13 at 16:19
    
I'm using ArcGIS 10.0. Actually I need to do a weighted mean. Thanks –  Tonalca Sep 13 '13 at 14:51
